Patent attributes
A liquid ejection method includes generating drive signals including ejection pulses, and applying the ejection pulses to an element that performs an operation for causing a liquid to be ejected. The element is provided corresponding to a nozzle. The nozzle causes the liquid to be ejected toward a targeted object. The generated drive signals are a first drive signal and a second drive signal. The first and second drive signals are generated simultaneously. The first drive signal includes a first ejection pulse for causing a liquid to be ejected to a targeted object, and the second drive signal includes a second ejection pulse for causing the liquid that has thickened in viscosity to be ejected outside the targeted object. When the nozzle is located above the targeted object, the first ejection pulse is applied to the element, and when the nozzle is located outside the targeted object, the second ejection pulse is applied to the element.
